I've just enabled avatars (20-128 pixels, max 24576 bytes), and twelve more styles (including three in the red/yellow family) for general use. To change your preferred style, go to 'User Control Panel' -> 'Board Preferences' -> 'My Board Style'.
(UPDATE): Disabled the serenity style, as users could not switch out of that style once in it. Sorry.
